CAP F011 FLASKS OR THE LIKE.

Application filed April 16,

The present invention relates to flasks or bottles such as thermosbottles or the like and has for its object to provide a cap thereforwhich can be used both as a drinking cup or as a funnel. to facilitatethe filling of the bottle.

My invention will be fully understood by reference to the accompanyingdrawing which forms part of this specification and in which similarreference characters denote corresponding parts, Fig. 1 being anelevation of a flask equipped with my improved cap which is shown inlongitudinal section; Fig. 2 a perspective view of the cap when used asa drinking cup; Fig. 3

shows the cap when used as a funnel and Fig. i a sectional View of acapof modified construction.

Referring to the drawing 10 denotes a metal flask which is provided withan externally threaded neck 10 to receive the metal cap and 11 denotesa. cork or other stopper. The metal cap 12 is provided at one end with athreaded portion 12 to screw on the threaded neck 10 of the flask and atits opposite end with an outwardly projecting hollow cylindricalextension 13 forming a nozzle of such diameter as to in the mouth of theneck 10 so that when placed over the neck in inverted position with itsnozzle 13 projecting inwardly through the mouth of the neck the cap 12will serve a funnel facilitating the filling of the flask. When it isdesired to use the cap as a drinking cup the stopper 11 is used totightly close the nozzle.

Instead of using the stopper 11 the outer end of the nozzle 13 may beprovided with a lid 14 which may be hinged to a ring 15 slidahl'ymounted on said nozzle as shown in Fig. i.

When the cap is to be used as a funnel the lid 14; is swung open andmoved together with the ring 15 toward the inner end of the nozzle. Whenthe cap is to be used as a drinking cup the ring is moved toward theouter end of the nozzle to bear against 1927. Serial No. 18 2194.

the upturned edge 13 thereof permitting the lid to be swung into closedposition. The lid 14 may be actuated by a spring (not shown) which tendsto swing it into closed position and. may be provided with tighteningmeans such as a. rubber or cork disk 16.

Since various other modifications may be made in the construction of mycap without departing from the principle of my invention I do not wishto restrict myself to the details described and shown.

What I claim is:

1.1 1s an article of manufacture, a capfor a flask having a threadedneck, said cap being adapted to be used interchangeably as a drinkingcup and funnel, and being formed at one end with a threaded portion toscrew on the threaded portion of said neck and at the opposite end withan open ended nozzle to fit in the mouth portion of said neck, and meansdisplaceably mounted on said nozzle for closing the latter when said capis used as drinking cup.

2. As an article of manufacture, a cap for a flask having a threadedneck and adapted to be used interchangeably as a drinking cup andfunnel, said cap being formed at one end with a threaded portion toscrew on the threaded portion of said neck and at the opposite end, withan open ended nozzle to fit in the mouth portion of said neck, a lid onthe outer end of said nozzle and an annular member slidably mounted onsaid nozzle to which said lid is hinged.

3. A combined drinking cup and funnel for a flask having a threaded neckportion comprising, a cap for said flask having an enlarged cup portion,and a reduced nozzle arranged at one end of said cup portion, a.threaded portion at the open end of said enlarged cup portion forengagement with said threaded neck portion, a lid on the outer end ofsaid nozzle and an annular ring slidably mounted on said nozzle to whichsaid lid is hinged.

In testimony whereof I afix my signature.
